In this engaging Lab-Aid, students model nucleic acids, the largest molecules found in living organisms. It is an excellent compliment to The Molecular Model of DNA and its Replication (LAB-AIDS‚® No.71). In this activity, the basic components of RNA and DNA are constructed. Students build the nucleotide which is composed of three parts: a five-carbon sugar, a phosphoric acid derivative called phosphate and a substance known as a nitrogen base. The parts are then linked together to form a DNA model. 12 complete sets of molecular model components are provided.
